Mexico • One peso
A Mexican Caballito peso at the matching 27.07 g/.903 standard contributes .7859 reference fine silver troy ounce. The actual issue years are 1910, 1911, 1912, 1913 and 1914. Identify the horse-and-rider design, UN PESO denomination and full date before using the calculator. The paired reference photograph depicts a 1911 specimen; neither the photograph nor a matching mass authenticates another coin.
When a fresh spot bid is available, melt values use fine-metal content × spot bid. CashForCoins guide buying offers use the separately configured percentage for each metal. Selected rare/numismatic coins require an appraisal. Dollar amounts remain unavailable when a fresh quote or buying percentage is missing.
Five actual KM453 Caballito years,1910–1914. Keep1911 lower-left ray lengths,1913 date spacing and1913/2 distinct. The1911 photo pair represents one unattributed ray subtype; the broader peso melt heading does not establish earlier Caballito issues.
Formula: specified fine-metal troy ounces × quantity. Dollar melt value additionally requires an approved current metal price.
The national-arms face shows the Mexican eagle-and-snake motif with ESTADOS UNIDOS MEXICANOS and UN PESO. Retain its complete inscriptions and mintmark in identification photographs. The reference describes this face as the obverse. Older Mexican silver pesos with a different national legend or cap-and-rays reverse require their own dated attribution even when their nominal silver content is similar.
A horse and rider face left against sun rays, with the date below. This is the identifying Caballito reverse. Its ray lengths and the spacing of the date can matter for variety attribution. Use the entire reverse together with the arms face; a cropped rider motif cannot establish date, denomination, alloy or authenticity.
The reference groups the Caballito under Estados Unidos Mexicanos and catalogs it as KM 453. Its dated table supports 1910–1914. The earlier 1866 opening date in the broader Mexico Silver Peso melt category does not describe the Caballito design. Later Mexican pesos use other weights, purities and designs; a one-peso denomination alone does not make those coins interchangeable for a metal-content calculation.
The matching nominal references are 27.07 g gross mass, 39 mm diameter and .903 silver fineness. Look for UN PESO, the national arms, the left-facing horse and rider, an actual 1910–1914 date and Mo attribution. Preserve both full faces and the edge for review. No edge inscription or thickness measurement is asserted from the inspected reference table. Plating, wear and a convincing photograph can complicate identification.
One matching Caballito contributes .7859 reference fine silver troy ounce. Three matching coins contribute 2.3577 fine silver troy ounces and 81.21 nominal gross grams. Calculations retain the reference’s rounded ASW input rather than replacing it with a specimen's measured weight. Nominal metal content is distinct from collector value, assay results and an actual purchase offer. Dollar melt pricing remains unavailable until an approved provider is connected.
Specific source-supported issue years: 1910–1914. The reference lists two 1911 reverse varieties distinguished by a short or long lower-left ray. It records both evenly and unevenly spaced 1913 dates and a 1913/2 overdate. These distinctions do not change the matching nominal .903 silver standard. The current photograph is a representative 1911 coin; its particular ray subtype must be assigned only after direct visual review, not inferred from its filename.
Keep the date, mint attribution, ray or spacing variety and any documented overdate with each specimen. Collector demand, surfaces, authenticity and condition may make a coin worth more than its nominal silver. Do not clean, polish or describe an overdate solely from a fuzzy digit. Retain established certification and provenance for a qualified appraisal.
Supply complete photographs of both faces and the edge, together with measured mass and diameter where available. The reference photo documents one 1911 design example and does not certify a coin offered for sale. Reproductions and altered dates require separate examination. A nominal 27.07 g mass or silver-colored surface alone cannot establish original manufacture or .903 fineness.
Separate Caballito pesos from other Mexican one-peso standards before counting a holding. Include the complete date and any supported 1911 ray or 1913 spacing/overdate attribution in an appraisal enquiry. The existing CashForCoins photo-appraisal workflow carries selected quantity into an enquiry without making an automatic purchase offer. A fine-metal calculation helps describe a collection; it does not replace inspection.
The reference designated Mexico Silver Peso group and dated Caballito KM 453 agree on 27.0700 g/.9030/.7859 fine silver troy ounce. The broader 1866–1914 melt heading includes other designs; this retained Caballito identity covers only actual 1910–1914 KM 453 annual rows. Diameter 39 mm comes from the dated type. No exact edge or thickness is independently approved here. The designated melt reference, KM 453 specifications and actual annual rows were inspected through public references on 2026-10-12. Only dated identity facts are used; no reference price table, mintage table or article is reproduced. Inri's genuine 1911 paired photograph has an independent CC 0 copyright-holder release in addition to the currency public-domain tag. Actual asset acquisition, complete-rim cropping and both-face visual review remain required before publication.
Both acquired 1911 faces retain the entire rim. The joined observed 960px image is split with margin cropping and WebP conversion, without enlargement, retouching or synthetic reconstruction. Its reverse ray subtype remains unattributed.
